Product Description:

The MHP115B-058-HG0-RNNNNN is a permanent-magnet servo motor supplied by Bosch Rexroth Indramat for the MHP Synchronous Motors series. The unit is built for precision positioning and speed regulation on packaging lines, gantry stages, and general automation axes where coordinated motion is required and electrical feedback is handled by a drive controller. This arrangement lets the motor serve applications that require repeatable motion during indexing, conveying, and synchronized machine cycles.

Under natural convection cooling, the motor can deliver a continuous standstill torque of 50.0 Nm, allowing it to hold heavy loads without external fans. The insulation system meets class F limits, so the windings may reach elevated temperatures without premature aging. Operation is specified for ambient conditions ranging from 0 to +40 °C, matching typical enclosed-machine environments. A die-cast housing and radial shaft seal provide ingress protection up to IP65, keeping dust and low-pressure water jets out of the stator chamber. Rotor position is monitored by an incremental encoder with 2048 increments, enabling tight velocity loops and fine index moves. Winding code 058 indicates the electrical resistance and inductance values that the matched drive must accommodate, and the housing relies on natural convection instead of forced airflow or liquid channels.

The mechanical interface is a plain shaft with a sealing ring, simplifying coupling to gear stages while maintaining internal lubrication. For applications that stop under motor torque alone, the unit is supplied without a holding brake, reducing mass and wiring. Power cabling attaches through a connector on the right side, streamlining layouts where multiple motors share a cable track. The frame belongs to size 115 and carries the length code B, giving moderate axial dimensions for its torque class.
